Sinclair's, Apple II's and the like on one of these modern LCD TV's.
Can they lock on to the cheap modulator signals or work with the
composite or RGB.
I'm thinking of getting rid of a bulky tv set and various rgb and black
and white monitors and use a modern solution.
I haven't tried anything as modern as a C-64, but an Elf w/CDP1861
will *not* work on one (nor on many CRTs made in the past 15 years)
because it isn't really "spot on" NTSC video - it's close, but only
close enough for old analog monitors.
From my experience, any display new enough to have
heavily integrated
components for locking onto the video does not like the output of
the
standard 1861 circuit (as seen in the original Popular Electronics
series on the 1802, the RCA reference design for the 1861, the Elf II,
the COSMAC VIP, the Spare Time Gizmos Elf2000, etc). I have had lack
of success with modern LCD monitors w/NTSC input, Apple 5" CRTs for
the Apple IIc, and a wide variety of recently-made displays. I have
had total success with B&W CRTs over 20 years old.
OTOH, for something slightly newer than an 1861, such as your examples
of the C-64, etc., I'd expect them to work with modern video hardware.
